What I expected to happen was that red wool would not be craft-able since there are no roses, therefore no rose red dye.
What actually happened was it was included in the crafting menu, but can't be crafted because we can't obtain rose red dye.
Steps to Reproduce:
1. Open up the crafting menu in either your inventory or a crafting table.
2. Select the decorations section.
3. Search for the red wool block and select it when you find it.
4. Notice that rose red dye is included in the recipe, but is not obtainable.
